Fajita Stuffed Chicken is a spicy and flavorful low-carb meal that's made in a single pan. Seasoned chicken breasts are stuffed with grilled onions, peppers, and cheese. Add sour cream and guacamole, and you've got a complete meal.
In a cast iron skillet over medium heat, add olive oil. Add diced bell pepper and onion and cook until lightly browned and onions are translucent, about 5 minutes. Remove from heat and set aside.
Butterfly your chicken breasts - hold your hand on top of the chicken breast and slice into the side of the chicken breast, cutting from one side to the other, leaving the opposite side intact. Your goal is to create a pocket for your filling.
Season chicken breasts with taco seasoning on both sides. Stuff chicken breasts with bell pepper, onion, and shredded cheese. Optionally, use toothpicks to keep the chicken breasts closed.
Reheat skillet over medium heat. Add more oil if needed. Sear chicken breasts on each side for 2-3 minutes per side, until browned.
Move skillet to oven to finish cooking for 12-15 minutes, or until juices run clear and internal temperature reaches 165 degrees Fahrenheit. Remove from oven and allow to rest for 2-3 minutes before serving.
Add any additional toppings to your chicken breasts before serving: guacamole, salsa, or more cheese.
